elasticsearch搜索数据
1.当我要搜索所有的数据可以这样
curl 'localhost:9200/bank/_search?q=*&pretty'
{
"took" : 10,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1000,
"max_score" : 1.0,
"hits" : [ {
"_index" : "bank",
"_type" : "account",
"_id" : "1",
"_score" : 1.0,
"_source":{"account_number":1,"balance":39225,"firstname":"Amber","lastname":"Duke","age":32,"gender":"M","address":"880 Holmes Lane","employer":"Pyrami","email":"[email protected]","city":"Brogan","state":"IL"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "6",
"_score" : 1.0,
"_source":{"account_number":6,"balance":5686,"firstname":"Hattie","lastname":"Bond","age":36,"gender":"M","address":"671 Bristol Street","employer":"Netagy","email":"[email protected]","city":"Dante","state":"TN"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "13",
"_score" : 1.0,
"_source":{"account_number":13,"balance":32838,"firstname":"Nanette","lastname":"Bates","age":28,"gender":"F","address":"789 Madison Street","employer":"Quility","email":"[email protected]","city":"Nogal","state":"VA"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "18",
"_score" : 1.0,
"_source":{"account_number":18,"balance":4180,"firstname":"Dale","lastname":"Adams","age":33,"gender":"M","address":"467 Hutchinson Court","employer":"Boink","email":"[email protected]","city":"Orick","state":"MD"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "20",
"_score" : 1.0,
"_source":{"account_number":20,"balance":16418,"firstname":"Elinor","lastname":"Ratliff","age":36,"gender":"M","address":"282 Kings Place","employer":"Scentric","email":"[email protected]","city":"Ribera","state":"WA"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "25",
"_score" : 1.0,
"_source":{"account_number":25,"balance":40540,"firstname":"Virginia","lastname":"Ayala","age":39,"gender":"F","address":"171 Putnam Avenue","employer":"Filodyne","email":"[email protected]","city":"Nicholson","state":"PA"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "32",
"_score" : 1.0,
"_source":{"account_number":32,"balance":48086,"firstname":"Dillard","lastname":"Mcpherson","age":34,"gender":"F","address":"702 Quentin Street","employer":"Quailcom","email":"[email protected]","city":"Veguita","state":"IN"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "37",
"_score" : 1.0,
"_source":{"account_number":37,"balance":18612,"firstname":"Mcgee","lastname":"Mooney","age":39,"gender":"M","address":"826 Fillmore Place","employer":"Reversus","email":"[email protected]","city":"Tooleville","state":"OK"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "44",
"_score" : 1.0,
"_source":{"account_number":44,"balance":34487,"firstname":"Aurelia","lastname":"Harding","age":37,"gender":"M","address":"502 Baycliff Terrace","employer":"Orbalix","email":"[email protected]","city":"Yardville","state":"DE"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "49",
"_score" : 1.0,
"_source":{"account_number":49,"balance":29104,"firstname":"Fulton","lastname":"Holt","age":23,"gender":"F","address":"451 Humboldt Street","employer":"Anocha","email":"[email protected]","city":"Sunriver","state":"RI"}
} ]
}
}
took参数表示的是话费的时间为10ms,
time_out表示这次查询是否设置了超时
_share告诉我们搜索了5个分片, 5个搜索成功了,0个失败
hits表示搜出的结果
total表示搜出了1000个结果
hits表示当前展示的结果,默认只有10条
上述那种方式可以用以下方式替换
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match_all": {} }
}'
2.如果我需要查询第二页的数据
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match_all": {} },
"from":10,
"size":10
}'
要注意条数是从0开始的
3.如果我需要按照balance进行降序排序
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match_all": {} },
"sort":{"balance":{"order":"desc"}}
}'
4.如果我只需要展示source中的两行字段account_number, balance
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match_all": {} },
"_source":["account_number","balance"]
}'
注意用方括号[]来括起两个字段
5.之前查询的数据都是匹配所有的,但是如果我只想匹配account_number为20的数据呢?
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match": {"account_number":20} }
}'
{
"took" : 40,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ {
"_index" : "bank",
"_type" : "account",
"_id" : "20",
"_score" : 1.0,
"_source":{"account_number":20,"balance":16418,"firstname":"Elinor","lastname":"Ratliff","age":36,"gender":"M","address":"282 Kings Place","employer":"Scentric","email":"[email protected]","city":"Ribera","state":"WA"}
} ]
}
}
可以看到之匹配account_number为20的数据,
6.那如果我想匹配address包含mill的数据呢?
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match": {"address":"mill"} }
}'
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 4,
"max_score" : 2.8025851,
"hits" : [ {
"_index" : "bank",
"_type" : "account",
"_id" : "970",
"_score" : 2.8025851,
"_source":{"account_number":970,"balance":19648,"firstname":"Forbes","lastname":"Wallace","age":28,"gender":"M","address":"990 Mill Road","employer":"Pheast","email":"[email protected]","city":"Lopezo","state":"AK"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "136",
"_score" : 2.4560115,
"_source":{"account_number":136,"balance":45801,"firstname":"Winnie","lastname":"Holland","age":38,"gender":"M","address":"198 Mill Lane","employer":"Neteria","email":"[email protected]","city":"Urie","state":"IL"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "345",
"_score" : 2.4560115,
"_source":{"account_number":345,"balance":9812,"firstname":"Parker","lastname":"Hines","age":38,"gender":"M","address":"715 Mill Avenue","employer":"Baluba","email":"[email protected]","city":"Blackgum","state":"KY"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "472",
"_score" : 2.4560115,
"_source":{"account_number":472,"balance":25571,"firstname":"Lee","lastname":"Long","age":32,"gender":"F","address":"288 Mill Street","employer":"Comverges","email":"[email protected]","city":"Movico","state":"MT"}
} ]
}
}
可以发现address只要包含mill就匹配出来,而且不区分大小写,但是之前我们设定account_number为20的,那么像200这样的应该也可以搜出来的啊?
这个其实是只要是字符串那么就是做匹配包含,如果是数值类型那么就是必须相等.
7.如果我想查出包含mill的或者包含lane的数据
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match": {"address":"mill lane"} }
}'
{
"took" : 15,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 19,
"max_score" : 3.3953483,
"hits" : [ {
"_index" : "bank",
"_type" : "account",
"_id" : "136",
"_score" : 3.3953483,
"_source":{"account_number":136,"balance":45801,"firstname":"Winnie","lastname":"Holland","age":38,"gender":"M","address":"198 Mill Lane","employer":"Neteria","email":"[email protected]","city":"Urie","state":"IL"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "970",
"_score" : 1.0273236,
"_source":{"account_number":970,"balance":19648,"firstname":"Forbes","lastname":"Wallace","age":28,"gender":"M","address":"990 Mill Road","employer":"Pheast","email":"[email protected]","city":"Lopezo","state":"AK"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "345",
"_score" : 0.888273,
"_source":{"account_number":345,"balance":9812,"firstname":"Parker","lastname":"Hines","age":38,"gender":"M","address":"715 Mill Avenue","employer":"Baluba","email":"[email protected]","city":"Blackgum","state":"KY"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "472",
"_score" : 0.888273,
"_source":{"account_number":472,"balance":25571,"firstname":"Lee","lastname":"Long","age":32,"gender":"F","address":"288 Mill Street","employer":"Comverges","email":"[email protected]","city":"Movico","state":"MT"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "449",
"_score" : 0.88407093,
"_source":{"account_number":449,"balance":41950,"firstname":"Barnett","lastname":"Cantrell","age":39,"gender":"F","address":"945 Bedell Lane","employer":"Zentility","email":"[email protected]","city":"Swartzville","state":"ND"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "742",
"_score" : 0.88407093,
"_source":{"account_number":742,"balance":24765,"firstname":"Merle","lastname":"Wooten","age":26,"gender":"M","address":"317 Pooles Lane","employer":"Tropolis","email":"[email protected]","city":"Bentley","state":"ND"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "231",
"_score" : 0.8275912,
"_source":{"account_number":231,"balance":46180,"firstname":"Essie","lastname":"Clarke","age":34,"gender":"F","address":"308 Harbor Lane","employer":"Pharmacon","email":"[email protected]","city":"Fillmore","state":"MS"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "921",
"_score" : 0.8275912,
"_source":{"account_number":921,"balance":49119,"firstname":"Barbara","lastname":"Wade","age":29,"gender":"M","address":"687 Hoyts Lane","employer":"Roughies","email":"[email protected]","city":"Sattley","state":"CO"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "631",
"_score" : 0.80940115,
"_source":{"account_number":631,"balance":21657,"firstname":"Corrine","lastname":"Barber","age":32,"gender":"F","address":"447 Hunts Lane","employer":"Quarmony","email":"[email protected]","city":"Wyano","state":"IL"}
}, {
"_index" : "bank",
"_type" : "account",
"_id" : "908",
"_score" : 0.80940115,
"_source":{"account_number":908,"balance":45975,"firstname":"Mosley","lastname":"Holloway","age":31,"gender":"M","address":"929 Eldert Lane","employer":"Anivet","email":"[email protected]","city":"Biehle","state":"MS"}
} ]
}
}
可以发现查出了19条数据,这种方式可以用下面这种方式替换
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": {
"bool": {
"should": [
{ "match": { "address": "mill" } },
{ "match": { "address": "lane" } }
]
}
}
}'
8.可是如果我要查询包含这个字符串"mill lane"呢?
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": { "match_phrase": {"address":"mill lane"} }
}'
{
"took" : 6,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 4.8004513,
"hits" : [ {
"_index" : "bank",
"_type" : "account",
"_id" : "136",
"_score" : 4.8004513,
"_source":{"account_number":136,"balance":45801,"firstname":"Winnie","lastname":"Holland","age":38,"gender":"M","address":"198 Mill Lane","employer":"Neteria","email":"[email protected]","city":"Urie","state":"IL"}
} ]
}
}
因此只需要把match替换成match_phrase即可.
9.但是如果我需要查询出既要包含mill,也要包含lane的数据呢?
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": {
"bool": {
"must": [
{ "match": { "address": "mill" } },
{ "match": { "address": "lane" } }
]
}
}
}'
可以发现和上述结果一样.
10.如果我要查询出既不能包含mill,也不能包含lane,可以如下
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": {
"bool": {
"must_not": [
{ "match": { "address": "mill" } },
{ "match": { "address": "lane" } }
]
}
}
}'
可以发现有981条
11.如果我需要查询年龄是40,而且state不是ID的数据
curl -XPOST 'localhost:9200/bank/_search?pretty' -d '
{
"query": {
"bool": {
"must": [
{ "match": { "age": "40" } }
],
"must_not": [
{ "match": { "state": "ID" } }
]
}
}
}'
{
"took" : 6,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 43,
"max_score" : 1.0,

} ]
}
}
可以发现查询到了43条
